Abstract

Abstract: Mixed-adsorption drying with zeolite is an option to improve driving force for drying corn. In this case, zeolite and corn are mixed and fluidized by air. The air will evaporate water from corn, whereas zeolite will adsorb water from the air. This paper discusses the effect of two types of zeolites (zeolite 3A, natural zeolite), and air temperature (30,40, 50oC), on the drying rate. At all cases, the presence of zeolites can improve drying rate up to 10-20% faster than that of drying without zeolite. The increase of zeolite percentage and air temperature can enhance drying rate.
